Precision oncology using liquid biopsies involves analyzing circulating tumor DNA (ctDNA) and other biomarkers in a patient's blood to detect and monitor cancer. This approach offers a non-invasive alternative to traditional tissue biopsies.
Liquid biopsies address the limitations of traditional tissue biopsies by offering a non-invasive method for detecting and monitoring cancer. They provide real-time information about tumor characteristics, enabling more personalized treatment strategies.
Liquid biopsies involve collecting a small volume of blood, which is then analyzed for the presence of ctDNA or cell-free tumor DNA (ctDNA). Advanced sequencing technologies identify specific genetic mutations associated with various cancers. These analyses can reveal early signs of cancer, monitor treatment response, and detect recurrence.
Manufacturing involves developing and validating liquid biopsy assays using advanced sequencing technologies. The process includes sample preparation, extraction of ctDNA, amplification, and sequencing. Quality control is crucial to ensure accurate results.
The build process typically starts with the development of a specific assay targeting known cancer-associated mutations. This is followed by extensive validation studies in clinical trials to demonstrate accuracy, sensitivity, and specificity. Once validated, the assays are scaled up for commercial production.
